determined by the higher of either the selected altitude or
the VNAV altitude programmed for the active leg in the
flight plan (Figure 11-3).
The color of the rectangular boxes may be magenta,
green, or white depending on the route of flight and
navigation source selected. The active GPS or GPS
overlay flight plan leg is represented by magenta boxes
that correspond to the Magenta CDI. A localizer course
is represented by green boxes that correspond to a green
CDI. An inactive leg of an active flight plan is represented
by white boxes corresponding to a white line drawn on
the Inset map or MFD map indicating an inactive leg.

SECTION 11 – ADDITIONAL
Pathways provide supplemental glidepath information
on an active ILS, LPV, LNAV/VNAV, and some LNAV
approaches. Pathways are intended as an aid to situational
awareness and should not be used independent of the
CDI, VDI, glide path indicator, and glide slope indicator.
They are removed from the display when the selected
navigation information is not available. Pathways are not
displayed beyond the active leg when leg sequencing is
suspended and are not displayed on any portion of the
flight plan leg that would lead to intercepting a leg in the
wrong direction.
Departure and Enroute
Prior to intercepting an active flight plan leg, pathways
are displayed as a series of boxes with pointers at each
corner that point in the direction of the active waypoint.
Pathways are not displayed for the first leg of the flight
plan if that segment is a Heading-to-Altitude leg. The first
segment displaying pathways is the first active GPS leg or
active leg with a GPS overlay. If this leg of the flight plan
route is outside the SVS field of view, pathways will not be
visible until the aircraft has turned toward this leg. While
approaching the center of the active leg and prescribed
altitude, the number of pathway boxes decreases to a
minimum of four.
Pathways are displayed along the flight plan route at the
highest of either the selected altitude or the programmed
altitude for the leg. Climb profiles cannot be displayed
due to the variables associated with aircraft performance.
Flight plan legs requiring a climb are indicated by
pathways displayed at a level above the aircraft at the
altitude selected or programmed.
